Specification of Letters Patent. Patented Aug. 29, 1922 Application filed June 16, 1919. Serial No. 304,565.

To aZZ whom it may concern:

Be it lrnown'that I, Josnrrr PLEASANT LITTLE, a citizen of the United States, residing at Statesville, in the county of Iredell and State of North Carolina, have invented a new and useful Subsoiler Attachment for Plows, of which the following is a specification.

The device forming the subject matter of this application is a sub-soiling attachment for plows, of that general type in which a bar'is connected to the beam of a low, a standard being carried by the bar, or vertical swinging adjustment. This invention aims to construct the harm such a way that it will be reinforced adequately, and to improve the construction of the standard, means being provided for preventing the standard from binding on the bar, said means exercising a two-fold ofiice, in that it serves not only as a spacer for parts of the standard, but, as well, serves as a means whereby the standard may be suspended in an inoperative position.

Figure 1 is a view partly in elevation and partly in perspective of a plow having my attachment applied thereto, the attachment being shown in elevated position in dotted lines;

Figure 2 is a top view of the attachment removed from the plow; and

Figure 3 is a side elevation of the attachment.

The numeral 5 designates a plow which includes a beam 6 and braces 7 extended from the beam to the handles.

ltfy sub-soiler attachment consists of a flat bar of stout metal indicated at 8 which is bent upon itself intermediate its ends as at 9 to form arms which are in contact with each other. The doubled bar 8 is offset intermediate its ends as at 10 so that the end 9 will be disposed directly behind the plow beam. I

A plow standard designated in general at 11 provided and is formed from a bar of flat stout metal bent to form parallel legs 12 and a downwardly extended foot 13 in which a plow share 14: is mounted in the usual manner. The ends of the legs 12 are pivotally connected with thefarms of the bar 8 adjacent the olfset 10 through the medium of a pivot pin 15. The rear end of the bar 8 is provided with a plurality of transverse apertures 16 and a removable pin 17 is extended through the legs 12 Y and through any one of the apertures 16, so that the standard 11 may be held against pivotal movement in desired adjusted position, to the end that the share 14 may penetrate the ground to different depths.

Extending transversely through the legs 12 intermediate their ends is a bolt 17 upon which is mounted a sleeve 18 the ends of which bear against the legs.

Depending from the sleeve'18 is a hook 19 which is capable of pivotal movement on the sleeve and is adapted to be engaged with one of the braces 7 to support the standard 11 in the position shown in dotted lines in Figure 1 when it is not desired to use the sub-soiler. In order to attach the bar 8 to the plow beams 6, pairs of clamping plates 20 are disposed upon opposite sides of the beam, one pair on the horizontally disposed further, is reinforced to receive the pivot element 15, and is reinforced for the reception of the apertures 16. The sleeve 18 ex ercises a double function, in that it forms a part of the suspension means for the standard 11, and serves, also, as a means for spacing the legs of the standard, to prevent the legs from binding on the arms of the bar 8.

What I claim as new is A sub-soiler attachment for plows, comprising a bar bent upon itself intermediate its ends to form side arms which are in contact with each other, the arms of the bar being provided with a plurality of apertures, and being offset laterally, the arms carrying a pivot element, the double-armed construction of the bar serving to reinforce the bar at the place where it is offset later- I the apertures in the arms; a share carried In testimony that I claim the foregoing by the standard; a combined spacing and as my own I have hereto alfixecl my signasuspension means disposed between the legs. .ture inthe presence of two Witnesses.
